The rarity of blue or violet-coloured Orchids has given a 
notoriety to this remarkable plant, which is the largest of 
the genus to which it belongs, and from the size and 
colouring of the flower by far the most showy. It would 
also appear to be a very free flowerer, as Mr. Backhouse 
of York, to whom I am indebted for ‘sending the fine 
specimen here figured, informs me that four and even six 
flowers occur on one shoot, and that twelve had been seen 
on one of his plants with three shoots, Unfortunately even 
a quarto plate would not give room to represent such a_ 
specimen. : 
Under B. Lalindei (t. 6331) I have expressed concurrence 
in the opinion that Bollea should, along with Pescatorea, be 
reduced to Zygopetalum; and I am glad to see that M. 
Reichenbach adheres to this view, for under the description 
of the present plant he says, ‘‘ Botanice Zygopetalum_celeste.” 
As to the native country of this plant, Prof. Reichenbach 
says, “It was discovered somewhere in western tropical 
South America, by M. Roezl, or by the Messrs. Klabock, his 
NOVEMBER Ist, 1879.
